Abstract: Yindongpo Gold Mine in Henan Province is the important super－large mixed hydrothermal gold deposit in our country.The certain physical difference of orebodies (ore vein groups),ore－controlling structure,magmatic,ore－bearing strata and their surrounding geological bodies is existed,the geophysical anomaly of them is significant.Through the interpretation of the deep IP anomaly of the mining area,the drilling verification of the low resistance and high polarizability anomalies is done.The location of deep orebody is in good agreement with the geophysical anomalies.Based on the above discussion results,according to the regional metallogenic types,the main industrial orebodies in the east of the deposit is saddle－like and stratiform distributed in Pt3W22 thick layer of carbonaceous sericite in quartz schist,due to the mineralized carbonaceous sericite quartz schist is characterized by low resistance and high polarizability,therefore,the IP characteristics of low resistance and high polarizability of mineralized carbonaceous sericite quartz schistis is the important prospecting indicator of the gold deposit in the mining area.

Key words: Gold deposit, Deep prospecting, Mineralized carbonaceous sericite quartz schist, IP anomaly, Prospecting indicator
